Yogurt is a food produced by bacterial fermentation of milk and the bacteria used to make it are known as "yogurt cultures". Most of them belong to probiotics such as Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus bacteria. Domestic fermented milk market is increasing and about 30 companies are producing yogurt. The purpose of this study was to analyze the quality characteristics of domestic commercial semisolid type yogurt. We collected 20 types of commercial yogurt at local markets. Physicochemical properties including pH, sugar content, acidity, viscosity and microbial characteristics of lactic acid bacteria counts were measured. The yogurt showed pH 4.5, 7.4~18.1% of sugar contents, 0.6~1.3% of total acids and 282~748 cP of viscosities. In the microorganism populations, lactic acid bacteria count were 6.5~11.5 Log CFU/mL and anaerobic lactic acid bacteria count were 7.2 ~ 11.1 Log CFU/mL. The quality characteristics were different depending on the constituents of the sample and the microorganisms used. These results are related to the quality characteristics of yogurts which are useful information about identifying new trends in domestic fermented milk industry.

Erwinia amylovora is a causative pathogen of fire blight disease, affecting apple, pear, and other rosaceous plants. Currently, management of fire blight relies on cultural and chemical practices, whereas it has been known that few biological resources exhibit disease control efficacy against the fire blight. In the current study, we found that an SFC20201208-M01 fungal isolate exhibits antibacterial activity against E. amylovora TS3128, and the isolate was identified as a Penicillium brasilianum based on the 𝛽-tubulin (BenA) gene sequence. To identify active compounds from the P. brasilianum culture, the culture filtrate was partitioned with ethyl acetate and n-butanol sequentially. From the ethyl acetate layer, we identified two new compounds (compounds 3-4) and two known compounds (compounds 1-2) based on spectroscopic analyses and comparison with literature data. Of these active compounds, penicillic acid (1) exhibited promising antibacterial activity against E. amylovora TS3128 with a minimal inhibitory concentration value of 25 ㎍/ml. When culture filtrate and penicillic acid (125 ㎍/ml) were applied onto Chinese pearleaf crab apple seedlings prior to inoculation of E. amylovora TS3128, the development of fire blight disease was effectively suppressed in the treated plants. Our results provide new insight into the biocontrol potential of P. brasilianum SFC20201208-M01 with an active ingredient to control fire blight.

Business organizations are asked to create new business models utilizing current technological innovations such as ubiquitous computing technology for developing new domains of business to obtain a competitive advantage and achieve a sustainable development. This study was focused on the processes for developing new and practical business models. The purpose of this study was to propose ubiquitous sport business modeling processes from the modeling framework. In particular, this study focused on developing new, pragmatic, and effective sport business models, and this new type of business is defined as 'u-sport.' For design the business model, extensive literature reviews and case studies were conducted for benchmarking the cases and expert group review was conducted for developing u-sport business model framework. The suggested business modeling processes in this study were consisted of four phases; 1) organization strategy level setting phase, 2) business strategy level setting phase, 3) business structure level setting phase, and 4) service level setting phase. The modeling processes were verified to adapt ubiquitous sport business. This designing and modeling process is expected to play a significant role on enhancing the technology-based business environments as the process mainly focuses on the service and consumer oriented approach rather than technology and suppliers oriented approach. In conclusion, establishing sport business models by adapting the service modeling process will deliver an exponential growth and development of future ubiquitous based industry.

Most of irradiated graphite that should be disposed comes from moderators and reflectors of nuclear power plants. The quantity of irradiated graphite could be higher in the future if high-temperature reactors (HTRs) will be deployed. In this case noteworthy quantities of fuel pebbles containing semi-graphitic carbonaceous material should be added to the already existing 250,000 tons of irradiated graphite. Industry graphite is largely used in industrial applications for its high thermal and electrical conductivity and thermal and chemical resistance, making it a valuable material. Irradiated graphite constitutes a waste management challenge owing to the presence of long-lived radionuclides, such as ¹⁴C and ³⁶Cl. In the ENEA Nuclear Material Characterization Laboratory it has been successfully designed a procedure based on the exfoliation process organic solvent assisted, with the purpose of investigate the possibility of achieving graphite significantly less toxic that could be recycled for other purpose [1]. The objective of this paper is to evaluate the possibility of the scalability from laboratory to industrial dimensions of the exfoliation process and provide the prototype of a chemical plant for the treatment of irradiated graphite.

Rural Development Administration (RDA) has developed a manufacturing technology which can increase the amount of platycodin D in Platycodon grandiflorum. A study is needed to estimate the value of this new technology and predict the market demand for a new product. This study estimates additional amount of willingness to pay (WTP) using contingent valuation method (CVM) for a new product with the technology that RDA has developed. The survey was created under virtual health functional foods market of Platycodon grandiflorums. It was conducted with 1,000 adult males and females aged between 19 and 59 years old in 17 major cities and provinces nationwide from December 4 to December 7, 2018. The amount of WTP for the health functional Platycodon grandiflorum was drawn using maxinum likelihood estimation method. The estimated average and median WTP values are 21,933.85 won per person and 10,000 won per person, respectively. The independent factors, including the ratio of monthly average health function food consumption to income, the average monthly income level of a household, and existence of family members or relatives engaged in food and nutrition-related professions in a household, have been shown to have a statistically significant influence on the WTP. This study presents the potential magnitude of health functional food market and the value of the new technology based on health functional food market.

The study demonstrated the pre-feasibility evaluation of the new agricultual technology R&D project and the ways to improve it. The study created new criteria for pre-feasibility evaluation based on the results acquired from the examination and analysis of pre-feasibility evaluation systems and criteria of various institutions at home and abroad in order to understand the current state of the evaluation method conducted by the Rural Development Administration and to seek ways for its improvement. The new criteria include indices for technicity, marketability, and feasibility. Based on these, questionnaires were prepared and the answers on them were statistically analyzed to set weights between indices. It was found that feasibility appeared the highest, in particular, feasibilities related to budget appropriateness, novelty, possibility of demand for the technology, and potential of commercialization appeared high. Referring to this conclusion, a simple operation process of pre-feasibility evaluation was introduced in the study.

I analyzed the relationships among motives, strategies, and performances of the university-initiated R&D activities in the Information Technology Research Center(ITRC) Projects. I suggested a research model and 3 hypothesis about them through analysis of a lot of literatures. And I also made an empirical test on the hypothesis through statistical methods. The data which were used in this analysis were gathered through a questionnaire survey to the head of R&D projects in the ITRCs. I would make several useful suggestions to the head of university's ITRCs and the policy makers. Firstly, the type of university's R&D strategy were influenced from several motives such as technology development and acquisition, co-utilizations of research facilities, and utilization and rearing of the expertise. Secondly, to select an optimal type of R&D strategy, the university should considered the efficient methods which were related to forecasting market size of new product and new technology, and to using the useful information on technology development, and to securing the expertise. Thirdly, the researcher and manager of ITRCs had to recognize the correct forecast of future market size of new product and new technology and a useful information about technology development, as the most important factors in improving performances of R&D projects. Lastly, They had to make an effort of getting the efficient methods to secure the expertise, research facilities, and rational compensation system.
